JOHN MARTINO, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO STUART ``& PETERSON, OF SAME PLAGE.

COAL-SIFTER.

Specification forming part of Letters Patent No. 47,768, dated May 16, 1865.

To all whom it may concern:

Be it known that I, JOHN MARTINO, of Philadelphia, Pennsylvania, have invented an Improvement in Cooking-Stoves; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists of a sieve with a handle and spout arranged in respect to the ash-chamber and grate of a cooking-stove, substantially as described hereinafter, so that by the aid of the said sieve the ashes may be readily separated from `the cinders and the latter deposited in the fire-place Without permitting the fine dust to escape into the room.

In order to enable others skilled in the art to make and use `my invention, I Will 110W proceed to describe the construction of the Same. V

On reference to the accompanying drawings, which form a part of this specification, Figure lis a side View, partly in section, of a cooking-stove with my improvements; Fig. 2, an end view, partly in section on the line 1 2, Fig. 1 Figs. 3 and 4, perspective views of the sieve.

The body A of the stove, the fines therein, the ash-chamber B, and tire-place D are similar, as regards forni, arrangement, and proportion, to those of ordinary cookinglstoves, there being at the top, near the front of the stove, the usual opening, E, provided with a door for the admission of the fuel, and in front of the grate a the usual sliding or other doors, C, for regulating the draft. In iront of the ash`chamber B are also suitable sliding doors, F. On the bottom of this chamber is placed a detachable ash-pan, zr, of sheetiron, and above the latter is the sieve G, Which consists of a cast-iron box open at the top, and having at the bottom a sheet, c, of suitable wire gauze or netting, or in place of the same an appropriate grate. The sieve has in front a spout, f,.which rests on the ledge g of the stove beneath the grate c, and from the front of the sieve projects an arm or handle, l1., adapted t0 a recess made in the front edge of the aslrchamber, the latter being furnished at the top with the usual detachable cover-plate, When the cinders and ashes have accumula-ted on the ledge g of the stove and on the spout f of the sieve, the plate t' is removed from the top of the ash-chamber, and both cinders and ashes raked onto the gauze or grate e of the sieve,

after which the cover i is replaced, and the sieve agitated by seizing the projecting handle h and moving it smartly backward and forward-an operation Which causes the finer ashes to pass through the gauze or netting of the sieve, while the cinders available as fuel remain. The presence of the cover i prevents the iiner ashes from escaping into the room when the sieve is agitated. After the ashes have been thus duly separated from the cinders the cover-plate i is removed, and the sieve withdrawn from its position in the ash-chamber and held in the position shown by red lines, Fig. l, so that its coni tents may pass into the opening E of the firechamber.

Although I prefer to arrange the sieve in the manner described, it Will be evident that the handle h of the sieve may project from one side of the same, as seen in Fig. 4, so that the agitation of the sieve maybe efected from the side of the ash-chamber, instead of from the front. The sieve, too, may be so constructed and arranged in relation to the ash-chamber and the recess in the edge of the latter for the reception ofthe handle h, so formed that a lateral vibrating motion as Well as a horizontal reciprocating motion may be imparted to the sieve.

I am aware that stoves have been hereto-l fore made With sieves arranged beneath the grate and admitting of being agitated; but

the sieves'have been heretofore of such a r character as to involve the necessity of a special and expensive construction of the stove for their reception, Whereas in my invention it is unnecessary to make the ashchamber larger than usual, or to alter it in shape.

I therefore do not claim, broadly, a detachable sieve situated within the ashvchamber of a cooking-stove and admittingof being there agitated 5 but I claim as my invention and desire to se-r name to this specification in the presence of eure by Letters Patenttwo subscribing Witnesses.

The sieve G, its handle h, and spout f, arv ranged in respect to the ash-chamber B and grate a of a cooking-stove substantially as Witnesses: and for the purpose herein set forth. JOHN WHITE,

In testimony whereof `I have signed my W. J. R. DELANY.

JOHN MARTINO.
